Separately, about 15 port truck drivers began a 24-hour strike at the port Monday, alleging their employer was trying to thwart their efforts to unionize, the Los Angeles Times reported.

Truckers contend that company supervisors have been illegally dissuading them from joining a union — an allegation the company has denied, the newspaper said.

The demonstration kicked off a week of planned actions by labor groups representing workers in several related industries, including logistics, the Times reported.

The move is the latest effort seeking to unionize drivers who move goods in and out of the sister ports of Los Angeles and Long Beach, which make up the largest U.S. port complex and handle more than 40% of Asian imports, the Times said.
